The Omnistore System

Riya let out a satisfied sigh as she curled up, and Kevin held her trembling body, his lips gently kissing her neck as they she basked in the aftermath of the intense orgasm she just had.

Kevin held her close and asked, "Feeling a bit less stressed now?"

Riya nodded, her face a bit sweaty, and looked into his eyes. "Yeah, thank you." She said despite she wasn't feeling stress but the orgasm still made her relaxed.

Kevin grinned mischievously and gave her a playful peck. "Then, how about you help me relieve my stress now?"

She gave him a slightly annoyed look, saying, "But you said I didn't have to."

With the most nonchalant expression, Kevin squeezed her breast as if it were the most ordinary thing to do with a sister. He turned her towards him and said, "Yeah, you don't have to do anything, other than let me suck on these." With that, he lifted her shirt, revealing her ample breasts that jiggled as they were freed from her clothing.

"Hold on, wait...are you kid? why would you wanna suck on my boobs?" Riya asked, her surprise evident as she attempted to cover her chest, but Kevin was persistent.

"I'm not asking you to 'stress me off,' But please let me suck them I really wanted to suck them from earlier," Kevin said with a pleading expression, his gaze fixed on her flushed face.

"Why? Nothing's going to come out from them, and I don't really feel comfortable when someone's sucking on them," Riya replied, her blush deepening.

Kevin remained stubborn, and with determination, he grasped her shirt, fully removing it. Before she could react, he held her breasts in front of her mouth and asked, "How would you know if it doesn't feel good? Have you ever had them sucked before?"

Riya was surprised but didn't stop him, trusting that Kevin wouldn't proceed without her consent. "Kevin, I said I don't want to."

"But don't you remember how good they felt when they were pinched and pulled? At least try licking them on your own," Kevin suggested, placing one of her firm nipples against her lips and gently rubbing it back and forth.

Her gaze fixated on her pink-colored bud, a part of her body she had never examined closely before, except for some playful teasing while self-pleasuring. Now, however, as she looked at them, they resembled smooth, delectable candies. A bit of saliva gathered in her mouth as she thought, 'It's not like trying it would do any harm.' With a hint of curiosity, she opened her mouth to let Kevin place it inside.

As she took the nipple into her mouth, she felt the warmth surrounding it. Seeking even more direct warmth, She let her tongue do it which was soon lacing it with warm saliva, creating a cozy sensation. Making it grew grew slightly in size, and as she continued to suckle, she experienced a unique pleasure, both in her nipple and in her mind, creating an unexpected sensation she had never felt before.

Many women have often wondered what's so special about breasts, that man like them so much. But Riya had never pondered this question herself. To her, breasts were just breasts, and there didn't need to be a specific reason to appreciate them. She had, on occasion, attempted to explore her girlfriends' chests but hadn't been entirely successful. Yet, in all her years, she had never thought of actually licking them. She had seen such actions in adult content, assuming it was meant to make things more provocative, but she had never fathomed the pleasure that could come from both giving and receiving such attention. Now, she understood why Kevin had wanted to lick and suck on them.

So, creating a gentle suction inside her mouth, Riya indulged in the sensation of sucking on her own nipple, making it even harder than before. She released it from her lips, and Kevin observed her with a playful smirk.

"It feels good, right? Now, try both of them together," he suggested, pressing her breasts against each other and guiding her nipples into her mouth simultaneously.

Riya showed no hesitation. Placing both nipples in her mouth, she first moistened them with her saliva. Then, using her tongue, she swirled and explored them, reintroducing them to her gentle sucking, causing both to achieve the same hardness and size.

While Riya was engrossed in sucking on her own nipples for a while now, Kevin abruptly pulled them from her mouth, pressing them against nipples his own mouth he declared, "Enough, it's my turn now."

With those words, he took one of her nipples into his mouth. Unlike her, he began by gently sucking and nibbling on them with his lips, his tongue swirling on top as he suckled.

"Ahh," escaped her lips as she watched Kevin's mouth expertly working her nipple, eliciting moans of pleasure from her as he suckled and fondled her ample breasts.

Riya didn't resist; it wasn't a big ask. All he wanted was to enjoy her breasts. She hesitated initially because she worried their sibling relationship would become even weirder, and it certainly was heading in that direction.

Kevin continued swirling his tongue against her nipple, tasting her saliva, and making her nipple tingle with excitement. Eventually, he withdrew one nipple from his mouth and pressed it against her lips, silently inviting her to reciprocate. Riya understood his unspoken request and started sucking on her nipples together with Kevin. She felt a sense of joy as they both pleasured her by sucking on her nipple

Sucking on her nipples, their faces were so close that their lips were just inches apart while they indulged in their intimate activity.

Kevin withdrew the nipple from his mouth and playfully licked her other breast the one in her mouth, then suggested, "Let's both suck on it together in your mouth." And gave a lick to her lips, which she parted slightly to allow his tongue to enter inside to trace her nipple inside her mouth. It felt to Riya like a form of kissing, a fact she hadn't quite realized, and she let Kevin's tongue venture into her mouth to engage with the nipple inside.
